Application ined February 1, 1926. Ysei-iai No. 85,290.

This invention relates generally to refrigerating apparatus and kconsists of certain novel features of construction', combinations and arrangements of parts'as will be hereinafter more fullydeseribed and lparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is aside elevation of an apparatus embodying our invention. i

Figure 2 is atop planview of our construction.` l

Figure 3 is a fragmentary section thereof.

Figure f is a detail view of a slightly modified form 'of condenser construction.V

Figure 5 is a fragmentary sectional View taken substantially on the line 5*-5 of Figure 2; and Figure 6 is a fragmentary end view of the condenser'.

Referring now to the drawings, 1 designates a stand having a substantially flat top 2 upon which we preferably mounta pump 3 for compressing a refrigerating medium, a motor 4f for driving thevpump, and a condenser 5 through which the compressed medium passes to be cooled and condensed be'A fore entering the usual brine tank `(not shown). In the present instance, the pump 3 and motor 4 maybe of any suitable construction'jand rare operatively connected by a short shaft 6 that carries a fan 7, while the condenser 5 comprises afserie's of oblong coils 8 that are preferably arranged in superposed relation upon a lrelatively large tube 9 an- Vchored in a suitable trough-'shaped recess'l() in the top 2 of the stand. As shown,-the uppermost coil 8 has a lateral extension 11 that is connected to the; purnp 3, while the lowermost coillias a lateral extension 12 that 'is preferably connected to a suitable nipple 13 projecting outwardly from the inner side of the tube 9. To provide an eflicient construction, the tubing forming the coils 8 and extension 11 and 12 has a relatively small diameter preferably g or M3 and is pro-l The tube 9 constituting the base for4 the coils v8 has a relatively large diameter land serves as a reservoir forv the condensed ree frigerating medium; As shown,k this tube is l provided witha sight opening 14 fordisclosing Vthe level of the refrigerating medium therein and has a suitable outlet'opening 15 through which therefrigerating medium may flow to a suitable tube (not shown) leadingto the brine tank. Preferably these openings 14 and 15 respectively are located in removable heads 16 and 17 at the opposite ends of the tube. Asshow-n, the sighto'peni'ng 14 in the head 16 is closed by a suitable piece of glass 18 which is heldin position by a Vgland dium in the system.

lTo provide a strong anddu'rable construction, the coils 8 'are preferably'held upon the tube 9 by means of a light sheet metal :frame 2Or while the tube 9 is preferably held inthe trough-shaped recess 1() by means' of the arcuate-shaped straps 21. As shown, the frame 2() is substantially U-'s'haped and is arranged in invertedposition Withinthe coils 8j To insure rigidity the sides 22 yof the frame 'are preferably corrugated to conform tothe curvature of suitable fins 23 surroundlower ends with inturned feet 24 that are rigidly secured, preferably by welding to the v top of the tube 9. The straps 21 preferablyy extend over the feet 24 and are terminally secured, preferably by the bolts 25, to the top 2 of the stand. Rigidly secured to the top 26 of the frame is a name plate 27 which constitutes a cover for the coils 8 and an anchorage plate for an inverted trough-shaped hood ding' the' tubing and are provided at .their 28. As shown, the top wall 29 of the hood is 5 and fan 7. When the apparatus is in operabe discharged toward the motor 4, hence the cooling and condensing of the compressed refrigerating medium passing through the radiator Will be expedited. Moreover .the constant flow of air Will tend to cool the pump 3 and motor a.

In Figure 3 We have shown a slightly Inodilied condenser construction in which the uppermost 'coils il', preferably the first three, are lorme'd ot 'r or 3/8 tubing, While the lower coils are preferably formed ol:l fg or l/SH- tubing. Thus this fig or 1/8 tubing will restrict lthe iloiv oil gases through the lower coils and will cause'the'iioiv of gases inthe -iand -/S tubing or" the upper coils to be retarded. As a result the or 1%, tubing will radiate lmore rapidly the heat of the reduced volume of gases passing therethrough, vivhi'lc the fg or /S tubing will have a better 'opportunity to radiate the -heat ot the larger volume of gases.

Vhile it is believed that from the toregoing description, the nature and advantage of our invention will b e readily apparent, ive desire to have it understood that ive do not limit ourselves to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

That We claim as our invention is:

l. In a refrigerating apparatus, the combination with a stand, of a condenser having atu-bular base secured thereto, a vplurality oi' coils of tubing arranged in superposed relation, and means for holding the coils in position including a frame secured tothe base.

2. In a reirigerating apparatus, the combination vWith a stand, o'f a condenser having a tubular base secured thereto, a plurality of coils of tubing arranged in superposed relation, and means for holding the coils in position including an inverted substantially U- shaped frame having feet secured to the base.

` 3. In a refrigerating apparatus, the combination With a stand, of a condenser having a tubular base secured thereto, a plurality of coils oii'tubing arranged in superposed relation, lins on said tubing, and means for holding the coilsin position including a traine Within the coils having corrugated portions engageable with said tins.

4. In a re'lrigerating apparatus, the combination with a stand, of a condenser having a tubular base secured thereto,a plurality of Vcoils'oi tubing arranged in superposed relation, and 'means `for holding the coils in position including a substantiallyV U-shaped Airame arranged in inverted position on the base, the top oi the frame `being above the uppermost coil and the sidesk oi the iframe being Within the coils and secured at their lower ends to the base.

5. In a rei'rigerating apparatus, the combination With a stand, of a condenser having a tubular base and a. plurality of coils of tubing arranged infsuperposed relation, means Ior'lwlding the coils in position including a iframe secured to the base, and means tor holding the base in position including a strap anchored on the stand embracing said base.

In a reirigerating apparatus, the combination "with a stand, of a condenser having a hollow base positioned upon the stand, a plurality ot' coils of tubing arranged in superposed relation, a'irame 'for holding the coils in position, land Vcommon means for securing said frame and hollow base upon the said stand.

7. In a reirigerating apparatus, the 'combination with a stand, ot a condenser having a tubularbase positioned upon the stand, a plurality oi coils of tubing arranged in su- )er osed relation a frame-tor holding said coils in position, and a strap embracingportions of said frame andl tubular base, said strap having laterally projecting portions rigidly secured to the stand.

In testimony whereof We aiiix our signatures.
